Answer:

C. 7 1/4 units

Explanation:

It can be useful to plot the points on a graph.

The two points are on the same horizontal line, so the distance between them is the difference of their x-coordinates.

4 3/4 -(-2 2/4) = (6 +2) +(3/4 +2/4) = 6 5/4 = 7 1/4 . . . . units

Some folks find it easier to do the arithmetic by converting to decimal numbers.

4.75 -(-2.50) = 4.75 +2.50 = 7.25 = 7 1/4 . . . . units
